217. Mother’s Day 2024 Superstorms: Tracing the Roots of Solar Eruptions Weeks Ahead

Contributed by Mausumi Dikpati. Posted on August 27, 2025

Multiple X-class flares and CMEs were produced by AR 13664/8 during the Mother’s Day week of 2024. This study suggests that predicting the locations of magnetically complex active regions, and studying and tracking their eruptive states using different proxy parameters can greatly improve the capability to forecast intense storms.

216. An “Average” Solar Active Region: Revealing Common Patterns in Magnetic and Flow Evolution

Each solar active region (AR) has its unique shape, size, and lifetime. In this work, the authors developed a method to ‘average’ bipolar ARs by normalizing their size, orientation, and timing, thereby revealing the typical properties of an AR and its evolutionary pattern.
